Gradient’s Patua site, near Fernley NV, is the company’s first geothermal power plant. Drilling at Patua recommenced in February 2010. Physical construction of the first 60 MW phase of the power plant will begin in the second quarter of 2011; and the anticipated date for commercial operations is the 3rd quarter of 2012.

“Gradient is pleased to achieve this significant milestone in the development of its Patua project,” said Craig Mataczynski, CEO. “The opportunity to partner with strong companies like SAIC and TAS will help make the project successful and support continued development of the geothermal industry.”

“SAIC is committed to developing renewable, economically attractive energy resources nationwide,” said J.T. Grumski, senior vice president and business unit general manager. “We look forward to working with Gradient and TAS to deliver the new plant, which will help tackle the growing need for a clean, reliable and secure energy supply.”

“TAS is excited to partner with SAIC and Gradient to build the largest binary plant that has ever been constructed,” said Craig Hurlbert, Chairman and CEO of TAS Energy Inc. “This is an opportunity for TAS to showcase our Advanced Supercritical Organic Rankine Cycle and improved air cooled design technology.”
